Fair enough. I just think this topic is a little too broad for hand histories to cover much ground, unless we go into like a hundred of them. One thing I'll point out is that all three of these are three-way action, not heads up to the flop, which makes a very big difference in the type of hands that are usually getting check-raised. Also, your 3rd hand here is a great example of someone getting aggro with a combo draw, which is why always mucking on the flop might not be wise (depending on the board texture). Raising those hands is so common now that it has become really hard to fold a good overpair on drawy boards like that - your equity is usually pretty high, whereas a few years ago it would have been lower because not that many people played draws that way.
